Analysis of X-Linked Dominant and Recessive Traits Suppose a couple, both phenotypically normal, have two children: one unaffected daughter and one son affected with a genetic disorder. The phenotype ratio is 1:1, making it difficult to determine whether the trait is autosomal or X-linked. With your knowledge of genetics, what are the genotypes of the parents and children in the autosomal case? In the X-linked case?
Ehler-Danlos syndrome is a rare disorder caused by a mutation ina gene that encodes a protein called collagen (type 3 A1). Collagenis found in the extracellular matrix that plays an important role inthe formation of skin, joints, and other connective tissues. Peoplewith Ehler-Danlos syndrome have extraordinarily flexible skin andvery loose joints. The following pedigree contains several individualsaffected with this syndrome, shown with black symbols. Basedon this pedigree, does the syndrome follow autosomal recessive,autosomal dominant, X-linked recessive, or X-linked dominantinheritance? Explain your reasoning.

Bloom syndrome is an autosomal recessive disease that exhibitshaploinsufficiency. A recent survey showed that people heterozygousfor mutations at the BLM locus are at increased risk of colon cancer.Suppose you are a genetic counselor. A young woman is referred to youwhose mother has Bloom syndrome; the young woman’s father has nofamily history of Bloom syndrome. The young woman asks whether sheis likely to experience any other health problems associated with herfamily history of Bloom syndrome. What advice would you give her?

Null mutations are valuable genetic resources becausethey allow a researcher to determine what happens to anorganism in the complete absence of a particular protein. However, it is often not a trivial matter to determinewhether a mutation represents the null state of the gene.a. Geneticists sometimes use the following test forthe nullness of an allele in a diploid organism: If theabnormal phenotype seen in a homozygote for theallele is identical to that seen in a heterozygote(where one chromosome carries the allele in question and the homologous chromosome is known tobe completely deleted for the gene) then the alleleis null. What is the underlying rationale for thistest? What limitations might there be in interpreting such a result?b. Can you think of other methods to determinewhether an allele represents the null state of a particular gene?

The color in Labrador retrievers is an example of epistasis. The two alleles for the pigment gene are: (B) for black coat and its recessive counterpart (b) for chocolate coat. A different autosomal gene affects the expression of color in the coat and has two alleles, (E), which allows the expression of color, and (e), which is epistatic and blocks the expression of the B/b gene. The epistatic allele is recessive and is only expressed as a yellow color in the homozygous condition (ee), regardless of the B and b genotypes. A completely homozygous black lab was mated to a yellow lab, homozygous for the chocolate allele. Their offspring will be the F1…

Jekyll-Hyde Afflicted Spider Curse Afflicted Jekyll-Hyde/Spider Curse I O Human 1 II 1 III 4. Jekyll-Hyde disease is characterized by transformation into an unfeeling, aggressive, alter ego at night. While the "Spider Curse" is a disease that causes affected individuals to grow extra arms and extra eyes during a full moon. The genes responsible for these diseases sort independently and both traits run in one family. Based on the above pedigree answer the following questions: What is the mode of inheritance for Jekyll-Hyde disease? (Hint: look at individuals III-1 & III-3) O a. Autosomal Dominant O b. Autosomal Recessive O c. X-Linked Dominant O d. X-linked Recessive What evidence supports your hypothesis? Give at least 2 pieces of information from the pedigree that support your answer to 3a.
